Bill Nye the Science Guy – Momentum
1.   Whenever something is _______________________, it has momentum.

2. What are the two factors that affect how much momentum an object has?

3. What happens when an object with momentum collides with a second object?

4. Bill Nye crashes a dump truck into a glass ornament.

a.   First, the truck crashes into the ornament and the ornament bounces off the front
of the truck. Where did the truck’s momentum go?

b. Then, the truck crashes into the ornament and the ornament crashes into a brick
wall. The ornament shatters and the pieces go flying everywhere. Where did the
truck’s momentum go?

5. If you are at rest, do you have momentum? Explain.

6. Why do rockets move? What does it have to do with momentum?
7. If a rocket has heavier fuel exhaust (water rather than air in Bill’s example), what happens
to the rocket? Why?

8. A tennis ball is placed on top of a basketball. The pair is dropped to the ground. What
happens when the basketball hits the ground? Why?

9. Why is a heavier bowling ball better for knocking down the pins?

10. Safety! When you are driving along and the car stop suddenly, you feel like you are thrown
forward. Why? Which of Newton’s Laws explains this phenomenon?

11. Can momentum be transferred from one object to a second object and then from the
second object to a third object? Give an example from the video.

12. Momentum is equal to mass multiplied by velocity. Therefore,

a.   Momentum is _________________ proportional to mass.

b. Momentum is _________________ proportional to velocity.
